Application led necemberl, 1909.

To all whom it may concern Be it known that 1, LINDSLEY Sonnen/tons, acitizen of the United States, residing 1n Hasbrouck Heights, county ofBergen, and State of New Jersey, have invented new and usefulImprovements in Electric llfixtures, of which the following is a'descriptlon My invention pertains to that class of electric fixtures orlighting apparatus adapted to contain an electric lamp or bulb anddirect the light therefrom ina desired manner and direction' and protectthe lamp or bulb from injury when .it is desired to use the same inexposed places. I

My invention has for its particular object to provide a fixture whichmay be used in railway cars adapted to be secured to the window panelalongside one of the seats "or in case of' sleeping cars in the cornerformed by the window panel and the usual berth partition.

A further object of my invention 1s to provide a fixture which willdirect the light of alamp in such manner that it will not shine upon theoccupant of the opposite seat where the seats are placed facing eachother as in sleeping cars.

A further object is to provide a lamp of such form and construction thatit may be fastened in place without necessitating cutting ofthewoodwork-that is, of such construction that the entire parts of thelamp or xture shall be self-contained and adapt` ed to be fastened Hushagainst the usual woodwork.

y invention is directed particularly to that class of fixtures in whichit is desired to use high enciency bulbs such as metallic lament bulbsand on this acount it is ad` vantageous that the bulb should always beheld with the filaments in a vertical position and that the switch orkey used for turning the lamp on and ed' should not subject the lamp tosudden shocks or vibrations which would tend to break the filaments.

ln the drawing Figure 1 represents an elevation of my improved fixtureas designed-for use in a corner as, for example, a corner formed by thewindow panel and the berth partition of an ordinary sleeping car towhich the same is shown applied. Fig. 2 is a vertical in a plane midwaybetween the two walls forming the corner shown in Fig. 1. i

follows: lly first fasten section of my improved fixture Patented dan.5, 1915. Serial No. 532,305.

In the drawing 1 represents the walls or partitions to which my Ifixtureis applied.

2 represents a back casting or frame secured to the walls as by thescrews 3. casting or back plate is provided /with an extension 4 adaptedto receive and hold in place the switch 5 and has fitted thereto thefront or removable portion 6 which carries the prismatic globe or bowl'i'. The removable portion 6 is extension 8 having two small gibs orhooks 9 adapted to pass through the opening 10 in the member 2 andengage the member as plainly shown in Fig. 2 in such manner that thescrew 11 when made up into the top of' the member 2 will hold the member6 firml rlhe bowl 7 is passed through the opening in the flanged portion12 of the member 6 and is provided with a flange enga mg the same asindicated. The bowl 7 is rmly held in place by a metallic ring 13 whichis passed under a couple of pins, one of which is indicated at 14C andthen caught at another point by the screw 15 carried by the lug or boss16.

17 is a web member carried by the mem ber 2 and having attached theretoa spring clip 18 so shaped as to rmly grip the soclret 19 and attachedto the member 17 as by screws 20. rlhe socket 19 thus firmly heldbetween the jaws of the spring clamp 18 is adapted `to hold the bulb 21in its proper position within the fixture.

22 v'represents a reflector adapted to direct the back rays of the lampso that they will pass ina desired direction through the prismatic bowl7. rlFhe reflector 22lis carried by the member 17 and attached theretoas by screws 23. v

24 represents a wire cleat carried by the member 17 and adapted to holdthe wires 25 in place, the said wires being connected with any suitablesource of current and with the lamp 21 through the switch 5.

26 represents apertures in the member 2 for the purpose of' properlyVentilating the xture.

'lo place my fixture in use l proceed as the back plate 2 in place uponthe walls 1 as by 'means of the screws 3, the proper. wires havin beenled to the roper location in the pane s. ll then connect 1the wireswitli the switch` 5 and the soclretI and then press the socket inprovided with'- a flange orplace between the jaws nof the spring clip1S. I then insert the bulb 21 in the ordinary manner and thenV place thebowl 7 in the front piece 6 as shown in Fig. 2, then place the ring 13.under the pins 14 and put in the screw l5 and tighten the same so as tobring the roper pressure upon the flange of the bowl I then insert thehooks 9 into the opening 10 until they en gage the back of the member 2.vI then swing the' upper part of the piece 6 into nearly a verticalposition and lift the same slightly toallow the screw 11 to clear the`member 2 until the said screw engages its threaded aperture in themember 2.` I then make up the screw 11 which presses the `member 6 intothe position shown in Fig. 2 and holds the same firmly in place. If thewires 25 are connected to thei proper source of current manipulation ofthe switch 5 will then turn the light on or olf and a snap movement maybe used in the switch without subjecting the filaments of the lamp 21 toany severe vibration owing largely to the flexible manner in which thelamp is held. If desired to remove the bulbl the screw 11 may be backedout and the front piece 6' swung away from the member 2 and lifted sothat the members 9 will disengage the back member 2 and then the piece 6removed. Then the bulb may readily be removed. or the socket taken fromits spring clip 18 if desired to permit of any examination of wiring,etc.

In practice I prefer to make the bowl 7 of such prismatic character thatthe refraction of the same will tend to concentrate the light given bythe bulb 21 into a conical shaped beam directed approximately 45 degreesbelow thejhorizontal and 45 degrees in the lateral direction from eachof the corner walls 1. When so directed the light in use in one cornerof a section of a sleeper will b useful to the occupant of the adjacentat and not annoying to the occupant of the seat opposite which is agreat practical advantage.

From the foregoing it will be plain that I have produced a fixture whichmay be applied to the corner formedby the window panel and the berthplar'tition in the ordi# nary sleeping car wit out cutting away of thepanel or artition to make clearance for portions o the fixture. Further.that I have produced a compact form of fixture' which will cause therays of the bulb or lamp contained therein to be directed in such manneras to be practically more useful than the ordinary exposed lamp used forthis purpose. Also that I have provided a fixture which may be readilyopened and f may be readily re cleaned and in which the parts needingrenewal or repair are easily accessible and laced and that my fixturehas Aself-contain?. therein' a switch in such position and so mountedthat it will not be heated to any appreciable extent by the heat givenout by the lamp and will not in its operation subject the filaments ofthe bulb to severe vibration.

I do not wish in any way to limit myself to the exact details ofconstruction shown in the accompanying drawing as it will be obviousthat considerable changes may be made in the design of my fixturewithout departing from the scope of the invention which is as set forthin the following claims:

l. Anv electric fixture having, in combination, an angular back-plate ofa form adapting it to be secured in a corner or angle, and formed at itslower end into a receptacle for a switch mechanism, and above saidreceptacle into a support for a lamp; a bowl-carrier partially closingthe front of said plate; Aand means for supporting the bowl-carrier atthe top of said back-plate, substantially as described.
